SATA Port Issue on A8 Max and AX8 Max

AX8 Max lists "1 × 16-pin FPC SATA port (supports 2.5-inch SATA hard drive)", but the manual does not explain how to use this port for physical connection.

The A8 Max and AX8 Max are shipped without a functional SATA port; some documentation information may be outdated. The AX8 Max uses an AMD 8000-series CPU. Both AMD 7000-series and 8000-series CPUs do not support SATA hard drives. Even if the port is fitted, the drive cannot be detected.
